The protocol was optimized following international recommendations and current practice in breast MRI [5,13]. Images were acquired in axial plane. B-values were: 50, 400, and 800 s/mm2. FOV: Field of view. TR, TE, TI: Repetition, echo, inversion time. T: Tesla. STIR: Short Tau Inversion Recovery. GRE: Gradient echo. SE: Spin echo. EPI: Echo planar imaging. SPAIR: Spectral adiabatic inversion recovery.
